Brothers avenge a father, Otherside and Earth fuse, a Death god strikes on Halloween...

Sean O’Farrell got smacked with a shocking vision. But there’s no time to process it. Sean’s brother arrives to help avenge their dad. The Celtic vampire queen will pay.

But the Morrigan brings bad news. Samhain, better known as Halloween, is only two days away. It's the night Tir na nOg and Earth overlap.

The perfect time for monster hordes to attack.

But Sean can’t protect the Bay AND find a cure for himself and all his friends. His only hope lies deep on the Otherside, but that leaves innocent lives vulnerable.

Meanwhile the Celtic god of death roams free, searching Sean’s city for what he lost.
